Aspheric lenses designed to suppress spherical aberration, coma, and astigmatism; extensively used in laser systems, imaging, and optical communications. A comprehensive product portfolio—spanning standard to ultra-high-precision grades—is complemented by tailored engineering solutions.
Product Overview
An aspheric lens is a high-performance optical component whose uniquely engineered surface profile overcomes the inherent limitations of conventional spherical optics. Unlike traditional spherical lenses—whose curvature remains constant across the aperture—an aspheric lens features a continuously varying radius of curvature, enabling light rays from the center to the periphery to converge precisely onto a single focal point. This fundamental design advantage effectively eliminates spherical aberration and coma at their source. Thanks to their superior optical performance and compact, streamlined form factor, aspheric lenses have become indispensable core components across demanding applications—including laser material processing, machine vision, medical instrumentation, and consumer electronics.
